texpackhelper

Tools for working with neural network-enhanced video game textures.

texpackhelper is designed to solve a set of issues that come from
using neural networks for creating high-resolution video game texture
packs from the original game files.

they look much better at higher resolutions. This process isn't perfect,
however, and could benefit from additional automation.

Enable snaps on openSUSE and install texpackhelper

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
